Harry Potter fans may enjoy this find. One of my favorite scenes of the series was in "Chamber of Secrets", when Tom Marvolo Riddle revealed his other identity. My friend Kcmcacher found another interesting anagram which you can read about while at this bonus. This letter play series is based on 15 letters, which were rearranged to make the words in these titles.
Directions to determine the final coordinates:
N40 AB.CDE W73 FG.HIJ
North Coordinates:
Step One : If the caches #3 & #4 were 5,3 then your AB coordinates are 55. If they were 5,5 then they are 57
Step Two: If the caches #5, #6 & #7 were 7,1, 7, then your CDE coordinates are 965. If they were 6, 6, 6 then they are 626
West Coordinates:
Step Three:
If the caches #10 and #11 were 5 & 6; then your FG coordinates are 55; if they were 5 & 5 then they are 56.
Step Four: If the caches #12 , #13 & #14 were 4,9,8 then your HIJ coordinates are 649; if they were 3,5,7 then they are 543
